SpeedBox2 for Giant 2017/2018 is revolutionary processor-controlled module what removes the speed limiter of your electric bike. Display shows real values! Values such as maximum speed, average speed, daily mileage and range are displayed correctly.

If you have a new bike with zero kilometres ridden, you have to drive about 1 kilometer before you install the SpeedBox.

The SpeedBox2 is activated by briefly pressing the WALK button located on the front of the control panel. After pressing this button, the current speed of 9.9 km/h is displayed on the control panel for about 3 seconds. This means that the SpeedBox2 is activated, and the motor support of the electric bike now works up to a speed of 99 km/h. When the WALK is pressed again, the current speed of 2.5 km/h is displayed. This means that the SpeedBox2 is deactivated, and everything works as it would if it weren't installed. The motor support of the electric bike now works up to a speed of 25 km/h.

Hi Jiri,
I'm interested in getting Speedbox 2 for my 2017 Giant Quick E+, Australian market version with Yamaha 500Wh / 80Nm motor.

Reading below I notice another customer has same bike seeking advice if Speedbox 2 would work - but wasn't answered. Just want to be sure Speedbox 2 will work with Giant Quick E+ before proceeding with purchase.

Could you confirm? Thanks. Andrew
